Last update 6 January Quote and Order boards in minutes on https: If you are looking for 3A adjustable power supply. Lm30 addition, it uses internal current limiting, thermal shutdown, and safe mode. To determine the output voltage, enter values for the program R 1 and set R 2 resistors and hit the “Calculate” button.

LM Datasheet 3A adjustable Regulator |

Also, its pin output connects the heatsink surface. Basic to use LM We love it because easy to use. A precision current regulator.

We can use the LM on a wide variety of applications. However, other values such as or ohms can also be used for R 1. Because it is the adjustable three terminal positive voltage regulator. Even small capacitors can have a low enough internal series resistance to be able to deliver 20A spikes when shorted.


As in the LM pinout above. It looks much like the popular LM You can buy at mouser.

If you want to try it. The adjustment terminal of the datashfet can be bypassed to achieve datashheet high ripple rejection. Normally, no capacitors are needed unless the device is situated more than mm 6 inches from the input filter capacitors in which case an input bypass capacitor is required. An optional output capacitor can be added to improve transient response. Which it looks like a popular LM The LM voltage regulators can provide up to 1.

Over and Under voltage protection of electrical appliances July 11, Simple Crystal oscillator Circuit using 74LS04 November 17, Transistor stereo bass booster September 15, The LM is best for you. Leave a Reply Cancel reply.

Plan to be about 3V about the desired output voltage. Where greater output current is required, the LM series regulators are suitable up to 3A and the LM series voltage regulators for up to 5A of output. We can set the output voltage with only two external resistors.


See the list below you may like it. Although the lmm350 is very short in duration, there is enough energy to damage parts of the regulator IC.

A programmable output regulator. We have many ways to make it. You don’t want to use too high an input voltage as the excess will need to be dissipated as heat through the regulator. Please update your bookmarks.

Since it has high current over 3A, we must mount the LM on the large heatsink. See the voltage regulator datasheets above for specific details regarding the dropout voltage and heatsink requirements. The LM may be boring for you. Solid tantalum capacitors can be used on the voltage output to improve the ripple rejection of the voltage regulator.

With connecting a fixed resistor between the adjust and output.

National Semiconductor

Many electronics circuits and projects for learning in simple ways. When external capacitors are used with a voltage regulator it may be necessary to use protection diodes to prevent the capacitors from eatasheet through low current points into the voltage regulator.

This is an LM Datasheet.
